0 Introduction
This document describes the Kretztechnik Voluson 730 Expert/Pro Ultrasound System’s conformance to the ACRNEMA DICOM (Digital Imaging and Communications in Medicine) standard and satisfies the DICOM requirement
for a vendor conformance specification.
The Voluson 730 Expert/Pro system is an ultrasound imaging device. The SonoView option of the Voluson 730
Expert/Pro system provides a means to select images and send them via DICOM to storage servers and printers.
0.1 DICOM Background
The DICOM information exchange specification provides a definitive structure of commands and information that
allow for the intercommunication of medical imaging devices. Developed by the American College of Radiology
(ACR) and the National Electrical Manufacturers Association (NEMA), the DICOM standard strives to promote
communication of image information through the use of a standardized set of command classes and information
semantics.
The DICOM standard defines classes of information that are common to many modalities of medical imaging.
However, to meet the specific needs of information content for such a diverse range of information, the DICOM
specification defines structures for a multitude of medical data. To alleviate the need for applications to implement
every aspect of the DICOM specification, a list of conformance tables for every modality was created to define the
minimum set of information necessary for data exchanges. A requirement of the DICOM specification is to maintain
a compliance document that outlines a subset of DICOM services and data classes that are supported by an
application. The purpose of this document is to define a subset of DICOM for the exchange of information with the
Kretztechnik Voluson 730 via its SonoView feature.
This document is written with respect to the ACR-NEMA Digital Imaging and Communications in Medicine
(DICOM) version number 3.0. For complete definitions of terms and acronyms in this document, please refer to the
Digital Imaging and Communications in Medicine (DICOM) Standard.

1 Implementation Model
The Voluson 730 SonoView feature incorporates the DICOM 3.0 standard for networked image printing and image
store functions. Images are transferred from the Voluson 730 ultrasound system using standard network connections
to be processed on a centralized printer or stored on a DICOM compliant file server.
1.1 Application Data Flow Diagram
The diagram below represents the SonoView’s Application Entities (AE) (in the boxes) and depicts the relationship
of the Application Entity’s use of DICOM to invoke real-world activities (shown on the right side).
There are two local real-world activities that occur in the Voluson 730 system – Image Send and Image Print. When
a user changes operation mode to image filing system from a live scanning session, the system will provide the menu
to send images to a network archiving server or print images to a DICOM compliant printer.

1.2 Functional Definitions of AE’s
Printing AE
This AE handles all aspects of the Print Management SCU.
Storing AE
This AE handles sending ultrasound images to a storage server using the DICOM Store SCU Services. In addition,
screen capture images can be sent using Secondary Capture SOP class.
Worklist AE
This AE supports the DICOM Basic Worklist Management Service as an SCU.
1.3 Sequencing of Real-world Activities
In order for any of the remote processes to be able to provide the Real World Activity SCP services which the
Voluson 730 system, an SCU, has requested, the appropriate association must have been previously opened. This
initiation occurs with the “Send” command in SonoView image store operations or “Print” in SonoView for image
print operations. In addition Send and Print requests can also be queued (using ‘Direct Send’ and ‘Direct Print’) . In
this case the queue manager will open an association and transfer the images in the background.
There are no other sequencing requirements.

Remarks: Internally the V730 Expert/Pro stores all images in color (RGB or YBR_FULL_422). Whenever a
destination is configured for MONOCHROME2 the images are converted on the fly and then transmitted. In this
case the SOP instance UID of the transmitted DICOM object is changed.

2.3 Worklist AE - Specification
The Worklist AE provides conformance to the following DICOM SOP Classes as an SCU:
SOP Class Name
Modality Worklist Information Model - FIND
SOP Class UID
1.2.840.10008.5.1.4.31
Conformance Level
Standard Extended
The Worklist AE will initiate an association when the user invokes the Search command.
2.3.1.1 General
28,672 bytes
Minimum PDU size accepted:
1,024 bytes
Maximum number of simultaneous associations: 1
The Worklist AE will not use asynchronous operations window negotiation.

"1.2.276.0.26.20010718.240"
Implementation Version name: " KRETZDICOM_240"
Notes: Version name above will be used initially but is subject to change with versions.
The Worklist AE will open association to the Worklist Server when the real-world activity occurs corresponding to
the user invocation of Search. The association is closed at completion of the query.
2.3.1.5 Association Initiation by: “Search”
The user invocation of “Search” will cause an association to be initiated to an Worklist server.
